APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday April 5, 2003 (MJD 52735) ---=== OBSERVING TEAM ===--- Night: Howard Brewington Steph Snedden ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- High wind and dust prevented us from opening until 08:00Z. But, then we started with spectro. Unfortunately, only plates were declard done because of bad seeing. Completed plates include: 1278 (cartridge 06) 1291 (cartridge 04) ---=== OBSERVING LOG ===--- 08:10Z plate 1278 (cartridge 06): Guide stars after gotoField, but had some problems finding the best focus with seeing at ~2.3" and large scale changes. Plate declared done in three exposures. 09:47Z plate 1291 (cartridge 04): One star on the edge of a fiber after gotoFleid. Seeing conditions deteriorated, i.e., 3.5" Four exposures were needed to complete this plate. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3847 23:58Z 00:15Z 100 O -97.35 -93.13 42 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 20279, plate -9999 ------- 23:52 20279 0.0 bias ----- sequence 20280, plate 1048 ------- 00:11 20280 10.0 flat 00:14 20281 2.0 arc 00:18 20282 2.1 arc 00:20 20283 2.1 arc 00:40 20284 2.1 arc 00:43 20285 2.1 arc 08:32 20287 2.0 arc 08:52 20288 900.1 target 09:09 20289 900.1 target 09:22 20290 600.1 target 09:30 20291 240.0 smear 09:33 20292 10.0 flat 09:36 20293 2.0 arc ----- sequence 20294, plate 1291 ------- 09:51 20294 10.0 flat 09:53 20295 2.0 arc 10:12 20296 900.1 target 10:24 20297 600.1 target 10:53 20298 1500.1 target 11:01 20299 240.0 smear 11:04 20300 10.0 flat 11:06 20301 2.0 arc 11:31 20302 1200.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 08:45Z 6 1278 223.15 0.0003 62.10 0.0030 63.25 -0.0154 1.000300 09:57Z 4 1291 221.67 -0.0007 77.31 0.0011 48.45 -0.0026 1.000200 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL6243 Stays: JL6244 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 23:53Z 7 0 0.99987 1283 2244 -100 121 30.0 7.6 30 265 08:44Z 6 1278 1.00030 -2961 -806 500 223 62.2 -1.6 20 282 2.3 09:57Z 4 1291 1.00020 -1974 -289 225 221 77.4 -2.4 20 285 2.2 10:36Z 4 1291 1.00017 -1678 -60 200 236 71.2 -2.8 6 359 3.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:30Z 47 5 21 243 (WSW) 1617 - scattered clouds 00:02Z 46 2 24 240 (WSW) 1300 - dust 01:07Z 42 -4 33 255 (WSW) 3079 - dust 01:39Z 40 -3 39 246 (WSW) 4333 - dust 02:11Z 40 -4 23 248 (WSW) 4338 - dust 02:43Z 39 -4 37 252 (WSW) 3445 - dust 03:15Z 38 -2 35 235 (SW) 2838 - dust 03:47Z 37 0 28 266 (W) 3050 - dust 04:19Z 36 2 28 266 (W) 2923 - 04:52Z 35 5 30 271 (W) 2255 - 05:24Z 33 10 20 268 (W) 2705 - 05:56Z 32 11 16 267 (W) 1695 - clear 06:28Z 31 12 26 267 (W) 1150 - clear 07:01Z 31 12 28 269 (W) 944 - clear 07:33Z 30 13 20 264 (W) 876 - clear 08:05Z 29 13 19 265 (W) 901 - clear 08:37Z 29 13 14 270 (W) 863 - clear 09:09Z 28 12 24 284 (WNW) 739 - clear 09:42Z 27 8 19 301 (WNW) 818 - clear 10:14Z 27 9 8 299 (WNW) 693 - clear 10:46Z 26 11 8 0 (N) 926 - clear 11:16Z 26 8 19 319 (NW) 525 - clear 11:46Z 25 7 23 334 (NNW) 671 - clear 12:18Z 26 5 17 305 (NW) 671 - clear ---=== TELESCOPE STATUS ===--- 01:25Z Raised the enclosure's pressure set-point because of high dust count. 07:50Z Enclosure doors opened, fans and blowers on, louvers opened. 08:00Z Enclosure off. 11:55Z Enclosure on, doors closed, fans and blowers off, louvers closed.
